Seems that versions for Digital Download are ready. So if you wish to avoid the massive rush hour when game comes out here is your medicine. Of course, this is the same deal at Starcraft II. You cannot install the game without salsa20 key which will be available on the release day. Since Blizzard's download service is not exactly top notch, I am already at 2 gigs for my region. No way I am going to download on the release day. CE is arriving but I wanna play since day 1 so I got myself a standard edition also

When I run the installer it asks me where to install and no matter where I choose it says "invalid path" and closes.

Edit: I chose my second hard drive and it actually started going. However, I want D3 on my C drive (SSD). Am I possibly downloading install files that I can then use to install anywhere? Or is the game actually installing on the drive I chose?
